Sen. Elizabeth Warren is facing a new round of criticism after the Washington Post reported Tuesday that she described her race as "American Indian" on her 1986 Texas Bar registration card.

The Massachusetts Democrat and 2020 presidential contender was widely condemned last fall when she released the results of a DNA test showing she had Native American ancestry.

The issue will likely continue to be a drag on Warren, who has faced fierce attacks from President Donald Trump over her racial identity.

Sen. Elizabeth Warren, the Massachusetts Democrat and 2020 presidential contender, is facing a new round of criticism after the Washington Post reported Tuesday that she described her race as "American Indian" on her 1986 Texas Bar registration card.

The registration card provides yet more evidence that Warren self-identified as Native American. However, there is no evidence that she benefited in any way from identifying herself as a person of color.

But Warren said her conversation with Bill John Baker, the principal chief of the Cherokee Nation, went beyond the DNA test.

"I told him I was sorry for furthering confusion about tribal citizenship," she told The Post. "I am also sorry for not being more mindful about this decades ago. We had a good conversation."

Some Native American leaders condemned Warren's choice to release a DNA test which found that the senator has a Native American ancestor between six and 10 generations ago. Theyargued that Warren had undermined "tribal interests" by claiming tribal heritage.

Warren took the bait in an apparent attempt to diffuse the right-wing attacks on her ancestral identity.

Soon after, she was forced to explain that she isn't claiming to be a racial minority or the member of a Native American tribe.

"I am not a person of color. I'm not a citizen of a tribe. Tribal citizenship is very different from ancestry," she said on the campaign trail in Iowa earlier this month. "Tribes and only tribes determine tribal citizenship and I respect that difference. I grew up in Oklahoma and like a lot of folks in Oklahoma, we heard the family stories of our ancestry."

Warren's most recent apology satisfied some Native American leaders, but not all. Some are calling on Warren to make a public apology on video.
